Ultimate Subaru Outback Transmission Maintenance Guide

Hi, neighbor! I’m very glad that you came to me with a question about servicing the transmission on your Subaru Outback. Now I’ll tell you everything based on my experience working at a car service center.

All you need to know about the transmission is that it needs to be serviced extremely rarely. The interval between fluid changes is approximately 60,000 miles. The transmission has a lifespan of up to 200,000 miles or more.

Let me remind you again, neighbor! With regular maintenance of your Subaru Outback, the risk of accidental breakdowns is reduced by 70%. Use this advice to be confident in your car.

Types of Transmissions in Subaru Outback

The Subaru Outback, like many vehicles, offers a variety of transmission options depending on the year, model, and market. The two most common types are the automatic transmission (AT) and the continuously variable transmission (CVT).

Year Range	Engine Type	Transmission Types
2000-2002	EJ Engines	Manual, Automatic
2003-2008	EJ Engines	Manual, Automatic, Continuously Variable Transmission (CVT)
2009-2012	EJ, FB Engines	Manual, Automatic, Continuously Variable Transmission (CVT)
2013-2018	FB Engines	Manual, Automatic, Continuously Variable Transmission (CVT)
2019-Present	FB, FA Engines	Manual, Automatic, Continuously Variable Transmission (CVT)

In the Outback line there are both unreliable and more reliable engines. We already talked about this once, if you forgot, come again for a cup of tea.

This table gives you an overview of the transmission options available for the Subaru Outback based on its production year and engine type.

Service Life of the Outback Transmission

The lifespan of your Subaru Outback’s transmission varies depending on factors like your driving style, operating conditions, and regular maintenance. Typically, these transmissions can last anywhere from 100,000 to 200,000 miles or even longer if well-maintained.

In simpler terms, if your Outback has an automatic transmission or a CVT, it’s important to avoid sudden and aggressive accelerations. These transmissions require smooth and gradual acceleration, which not only prolongs their life but also improves fuel efficiency.

Common Transmission Problems in Subaru Outback

While the Subaru Outback is a reliable vehicle, some owners have reported issues related to the automatic transmission or CVT. These problems can include jerky gear shifts, vibrations, transmission fluid leaks, and more. It’s worth noting that these issues are not unique to the Outback and can occur with any car equipped with an automatic transmission.

Checking Transmission Fluid Level

Regularly checking the transmission fluid level is a crucial part of transmission maintenance. To do this:

1. Park your car on a level surface with the engine running.
2. Open the hood and locate the transmission fluid dipstick.
3. Pull out the dipstick, wipe it clean, and reinsert it.
4. Remove the dipstick again and check the fluid level against the markings. It should fall within the recommended range.

Fluid Change Interval

The frequency of changing the transmission fluid in your Subaru Outback can vary based on the model and driving conditions. Typically, it’s recommended to change the fluid every 30,000 to 60,000 miles. Factors influencing the interval include your driving style, vehicle load, road conditions, and climate.

Signs of the Need for Fluid Change

Consider changing the transmission fluid if you notice:

• Increased noise or vibrations during gear shifts.
• Difficulty shifting gears or jerking during acceleration.
• Leaks or fluid seepage under the car.
• Elevated transmission temperature.

What Else to Replace with Transmission Fluid

When changing the transmission fluid, it’s a good idea to inspect and replace the transmission filter if needed. This helps maintain the cleanliness and efficiency of the transmission.

Choosing Transmission Fluid

When selecting transmission fluid for your Subaru Outback, always follow the manufacturer’s recommendations as outlined in your user manual. It’s essential to use compatible fluid with the correct viscosity and specifications based on your vehicle’s year and engine type.

Here’s a summary of recommended transmission fluid based on engine type and specifications:

Year Range	Engine Type	Recommended Transmission Fluid	Fluid Capacity	Suitable Brands
1998-2008	EJ25D Engines	DEXRON®-III	4.75 quarts	Toyota DEXRON®-III ATF, Castrol DEXRON®-III ATF
2009-2013	FB25 Engines	DEXRON®-VI	6.3 quarts	Valvoline DEXRON®-VI ATF, Mobil 1 DEXRON®-VI ATF
2014-Present	FB25 Engines	CVT Fluid	3.5 quarts	Subaru Genuine CVT Fluid, Valvoline CVT Fluid

This table provides an overview of the recommended transmission fluids for each engine type in the specified year ranges for the Subaru Outback, along with fluid capacity and suitable brands.

I already told you once about the most common problems of Subaru Outback owners. If you are still asking the price and considering buying this car, take a look when you have time.

Fluid Replacement

When it’s time for a fluid change, you’ll need some tools and follow these steps:

Required Tools

• Wrenches for bolt removal.
• Container for old fluid.
• Transmission filter (if needed).
• New transmission fluid.

Step-by-Step Instructions

1. Lift the front of your car and secure it properly.
2. Disconnect hoses and connectors that link the transmission to the vehicle.
3. Remove the bolts securing the transmission to the engine.
4. Carefully lower the transmission and remove the old fluid.
5. Inspect the condition of the transmission filter and replace it if necessary.
6. Refill with new transmission fluid through the dipstick, following the recommended level and type.
7. Lift the transmission back into place and secure it with bolts.
8. Reconnect hoses and connectors to the transmission.
9. Start the engine and ensure that the transmission shifts correctly.
10. Perform a leak check and ensure all components are in place.

If you still want to service your car yourself, change the engine oil and filter in 15 minutes – see my instructions here.
